These Sockwell men's sprint micro socks are great for your running activities. To use them, simply put them on like you would with any other socks. Make sure to choose the right size according to the size guide provided. When it comes to maintenance, you have two options. For an easy wash, turn the socks inside out, machine wash them in warm water, and tumble dry on low heat. But remember, don't bleach them. If you want to be more environmentally friendly and take better care of your socks, you can machine wash them in cold water and air dry. Also, if you're in between sizes, it's better to size up for a more comfortable fit.
